CI log is sparse and does not give any clue to debug

Project Member Reported by uekawa@google.com, Jul 6

Issue description

https://chromium-review.googlesource.com/c/chromium/src/+/1124201
failed with:
 https://ci.chromium.org/p/chromium/builders/luci.chromium.try/cast_shell_linux/87450

I think the log is:
https://logs.chromium.org/v/?s=chromium%2Fbuildbucket%2Fcr-buildbucket.appspot.com%2F8941773466961015168%2F%2B%2Fsteps%2Fcast_shell_browsertests__retry_summary_%2F0%2Fstdout
step returned non-zero exit code: 1



Failure reason:
1 out of 1 aggregated steps failed. Failures: Step('cast_shell_browsertests (retry summary)') failed with return_code 1



This is not enough to understand what is going on.


 
Components: Infra
looking a bit more, maybe 
cast_shell_browsertests (without patch)
and 
cast_shell_browsertests (retry summary)  
should be given more proximity, and if there's a diff of two that would be more helpful to understand what is going on.

Moving to CCI, please pass to Infra>Platform if this should be handled at a lower level.

Any step with the text "(retry summary)" in its name isn't going to contain any useful debugging information. It just prints the list of individual tests that failed with your patch applied and subsequently succeeded without the patch applied. Since that list is nonempty in the given build, you'll want to find the test that failed with the patch applied. In this case that would be the step "cast_shell_browsertests (with patch)". Its log would be:
https://logs.chromium.org/logs/chromium/buildbucket/cr-buildbucket.appspot.com/8941773466961015168/+/steps/cast_shell_browsertests__with_patch_/0/stdout

Unfortunately, it seems bug 795156 has eaten that log, so we can no longer see how it failed. I suspect it would have looked like:
https://logs.chromium.org/logs/chromium/buildbucket/cr-buildbucket.appspot.com/8940181849667868080/+/steps/cast_shell_browsertests__with_patch_/0/stdout

Which should be enough to debug any failures you come across, so closing this out. Feel free to reopen if I missed something.
